No deposit fee. A flat 1 USDC withdrawal fee, regardless of amount.
Deposits
USDC arrives through the Arbitrum bridge. Hyperliquid takes nothing on the way in; you pay Arbitrum gas to send the transaction, typically a few cents.
Withdrawals cost 1 USDC
Flat, not percentage. Withdrawing $50 costs 1 USDC — 2%. Withdrawing $5 million costs 1 USDC — effectively nothing. The structure penalises frequent small withdrawals and is irrelevant at size.
Some searches ask about a 1% withdrawal fee. There isn’t one. The figure is 1 USDC.
Settlement back to Arbitrum typically takes a few minutes once the queue processes.
Vault deposits and withdrawals
Depositing into or withdrawing from a vault carries no additional fee. Vaults charge a share of profit, which is a different thing — see vault fees.
The cost that actually matters
Deposits and withdrawals are the smallest line. Trading fees on notional and hourly funding dominate, and for anyone holding a position rather than round-tripping it, funding is the larger of the two.
